[pstricks] Questions about grids

[Philippe Delavalade]

Hello everybody.

I'm new on this mailinglist but I use pstricks from time to time since many
years.

I would like to draw a grid with dotted lines and without any labels.

With \psgrid[linestyle=dotted,...] I have no error message but lines of the
grid are not dotted :-(

For the labels, I tried gridlabels=0pt but maybe there is something more
convinient ?

Thanks in advance for tips.
